Scraped wheels can be an eyesore, diminishing the overall appearance of your vehicle. Whether it’s caused by curb rash, accidental impacts, or everyday wear and tear, fixing scraped wheels can restore them to their original condition and protect them from further damage. In this guide, we’ll walk you through how to fix scraped wheels, making them look as good as new.
What Are Scraped Wheels or Curb Rash?
Scraped wheels, often referred to as curb rash, occur when the edge of a wheel comes into contact with a hard surface like a curb, causing scratches, scuffs, or gouges on the wheel’s finish. This type of damage is usually superficial but can affect both the appearance and the integrity of the wheel over time if left untreated. Curb rash is a common issue for drivers and is more likely to occur during parking maneuvers or on narrow streets. Recognizing and addressing curb rash early can prevent further deterioration and maintain the value of your vehicle.
Types of Wheel Damage
Wheels can suffer from a variety of damage types beyond curb rash, each with its own causes and implications. One common type is corrosion, which occurs when wheels are exposed to moisture and road salt, leading to rust and weakening the wheel over time. Another issue is bent rims, often resulting from hitting potholes or other road hazards, which can compromise driving safety and lead to uneven tire wear.
Cracks in the wheel are another serious concern, typically caused by high-impact collisions, and can potentially cause air leaks or even wheel failure. Finally, paint or finish damage, such as peeling or fading, not only detracts from the wheel’s aesthetic appeal but can also leave the metal underneath exposed to environmental damage. Identifying and addressing these problems promptly is crucial for maintaining both the look and performance of your wheels.
Tools and Materials Needed
To effectively inspect and maintain your wheels, you’ll need the following tools and materials:
- Tire Pressure Gauge – For checking and adjusting tire pressure.
- Torque Wrench – To ensure lug nuts are tightened to the manufacturer’s specifications.
- Wheel Cleaner and Brush – For removing dirt, grime, and brake dust without damaging the finish.
- Microfiber Cloths – For safely wiping down wheels and preventing scratches.
- Flashlight – To aid in identifying cracks or other damage in hard-to-see areas.
- Sandpaper or Metal File – For smoothing out minor surface blemishes.
- Wheel Paint or Clear Coat – To repair or touch up damaged finishes.
- Jack and Jack Stands – For safely lifting and securing your vehicle during inspection or repairs.
Having these tools and materials readily available will simplify the process of addressing wheel issues and help ensure optimal performance and appearance.
10 Methods How to Fix Scraped Wheels
1. Clean the Wheel Thoroughly Before Repair
Before addressing any damage, it’s essential to clean the wheel completely. Use a wheel cleaner and a stiff brush to remove dirt, brake dust, and road grime. Scraped areas tend to hold onto debris, which can interfere with fillers, sandpaper, or paint adhesion. After scrubbing, rinse and dry the wheel with a microfiber cloth. For stubborn residues, wipe the area with isopropyl alcohol. A clean surface ensures the repair products bond properly and that you’re accurately assessing the full extent of the damage.
2. Sand Down the Damaged Area with Fine Grit
Once the wheel is clean, begin the repair by sanding the scraped area using fine-grit sandpaper—typically starting with 240 or 320 grit. Sand in a circular motion to level the scratched metal and remove any jagged edges or high spots caused by the scrape. For deeper gouges, you may need to use a lower grit like 180 briefly before switching back to finer grades to smooth it out. The goal is to feather the damaged zone into the surrounding metal for a uniform appearance.
3. Use a Metal or Alloy Wheel Filler
For scrapes that have gone deeper than just surface scratches—especially on alloy wheels—a specialized metal filler or epoxy putty designed for automotive rims should be applied. Mix the compound per the manufacturer’s instructions and use a plastic applicator to spread it evenly over the gouge. Press firmly to fill all indentations. Once dry (usually after 15–30 minutes), sand it smooth using 320–600 grit sandpaper until the repaired area blends seamlessly with the rest of the wheel.
4. Wet Sand for a Smooth Finish
Wet sanding helps achieve a professional-looking finish by reducing surface imperfections left by dry sanding. After shaping with filler, soak 800 to 1000 grit sandpaper in water and gently sand the area. Keep the surface wet and use light pressure. Wet sanding removes tiny scratches and prepares the surface for primer and paint. Rinse and dry the area afterward. For an ultra-smooth result, finish with 1500 or 2000 grit paper before painting.
5. Apply Automotive Primer to the Repaired Spot
Primer is crucial for ensuring that the paint sticks properly and that the wheel surface is sealed. Use an automotive-grade self-etching or filler primer, and apply it in thin, even coats over the repaired section. Hold the spray can about 6–8 inches away and allow each coat to dry before applying the next. Typically, 2–3 coats are sufficient. After the final coat dries, lightly sand the area with 1000 grit paper to smooth any unevenness and prepare for color matching.
6. Match and Apply Wheel Paint
Choosing the right paint is vital for an invisible repair. Many automotive stores sell wheel-specific touch-up paint in common OEM colors like silver, gunmetal, or black. If unsure of your exact color, you can find it by checking the vehicle’s paint code or consulting the wheel manufacturer. Apply the paint in thin layers, allowing 10–15 minutes between coats. It’s better to apply several light coats than one heavy one, as this avoids drips or uneven buildup. Feather the edges to blend with the existing wheel color.
7. Finish with a Clear Coat for Protection
Once the base color has dried thoroughly (usually after an hour or two), apply a clear coat to protect the paint and provide a uniform sheen. Use a wheel-specific or automotive clear spray, and apply it just like the color coat—in thin, even layers. Three to four coats will usually provide adequate protection. The clear coat also helps hide blending lines and gives the wheel a factory-finished look. Allow the clear coat to cure for at least 24 hours before washing or waxing.
8. Buff and Polish the Entire Wheel
After the clear coat has fully cured, use a polishing compound and a microfiber cloth or power buffer to polish the repaired area and the rest of the wheel for a consistent shine. Buffing removes any dullness from the clear coat and helps merge the repaired zone with the original finish. If needed, finish with a fine polish or wheel wax to enhance gloss and provide a protective layer against road grime and brake dust.
9. Use a Wheel Touch-Up Kit for Minor Scrapes
For light scrapes or quick fixes, a wheel touch-up kit may suffice. These kits typically include sandpaper, primer, paint, and clear coat—all matched to standard wheel finishes. Ideal for minor curb rash, these kits provide a simple, cost-effective way to restore wheel appearance without removing the wheel from the car. The step-by-step instructions make them beginner-friendly, and they’re perfect for temporary repairs or less visible wheel damage.
10. Consider Professional Refinishing for Extensive Damage
If your wheels have deep gouges, cracks, or you’re uncomfortable attempting a DIY repair, professional refinishing might be the best option. Wheel repair shops use specialized tools, CNC machining, and powder coating for durable and flawless results. While more expensive than a home repair, a professional service ensures long-lasting repairs, especially for expensive or high-performance wheels. In cases where structural integrity is compromised, expert inspection is strongly recommended before continuing to use the wheel.
Things to Consider When Refinishing Wheels
- Extent of Damage
Assess the damage to your wheels before deciding on a refinishing method. Minor scratches or scuffs can typically be handled with DIY solutions, while larger cracks or deep gouges might require professional assistance.
- Cost vs. Value
Consider the cost of refinishing compared to replacing the wheels. For older or budget wheels, replacement might be more economical, whereas high-performance or custom wheels are often worth the investment for professional refinishing.
- Durability of Repairs
Evaluate the longevity of the refinishing solution. DIY repairs may be a temporary fix, but professional refinishing with powder coating or CNC machining provides a more durable and lasting outcome.
- Safety Concerns
If the wheel’s structural integrity is in question, prioritize safety over aesthetic improvements. Have a professional inspect the wheel to ensure it is safe for use.
- Time Investment
Refinishing wheels, whether DIY or professional, requires time. DIY methods demand careful preparation and application, while professional services may involve a waiting period for completion.
Taking these considerations into account will help you choose the best route for refinishing your wheels, ensuring a balance between cost, durability, and safety.
